@function SecCodeGetStatus
Retrieves the dynamic status for a SecCodeRef.
The dynamic status of a code can change at any time; the value returned is a snapshot
in time that is inherently stale by the time it is received by the caller. However,
since the status bits can only change in certain ways, some information is indefinitely
valid. For example, an indication of invalidity (kSecCodeStatusValid bit off) is permanent
since the valid bit cannot be set once clear, while an indication of validity (bit set)
may already be out of date.
Use this call with caution; it is usually wiser to call the validation API functions
and let then consider the status as part of their holistic computation. However,
SecCodeGetStatus is useful at times to capture persistent (sticky) status configurations.
@param code A valid SecCode object reference representing code running
on the system.
@param flags Optional flags. Pass kSecCSDefaultFlags for standard behavior.
@param status Upon successful return, contains the dynamic status of code as
determined by its host.
@result Upon success, noErr. Upon error, an OSStatus value documented in
CSCommon.h or certain other Security framework headers.

@function SecCodeCopyInternalRequirement
For a given Code or StaticCode object, retrieves a particular kind of internal
requirement that was sealed during signing.
This function will always fail for unsigned code. Requesting a type of internal
requirement that was not given during signing is not an error.
Specifying a type of kSecDesignatedRequirementType is not the same as calling
SecCodeCopyDesignatedRequirement. This function will only return an explicit
Designated Requirement if one was specified during signing. SecCodeCopyDesignatedRequirement
will synthesize a suitable Designated Requirement if one was not given explicitly.
@param code The Code or StaticCode object to be interrogated. For a Code
argument, its StaticCode is processed as per SecCodeCopyStaticCode.
@param type A SecRequirementType specifying which internal requirement is being
requested.
@param flags Optional flags. Pass kSecCSDefaultFlags for standard behavior.
@param requirement On successful return, contains a copy of the internal requirement
of the given type included in the given code. If the code has no such internal
requirement, this argument is set to NULL (with no error).
@result On success, noErr. On error, an OSStatus value
documented in CSCommon.h or certain other Security framework headers.

@function SecCodeSetDetachedSignature
For a given Code or StaticCode object, explicitly specify the detached signature
data used to verify it.
This call unconditionally overrides any signature embedded in the Code and any
previously specified detached signature; only the signature data specified here
will be used from now on for this Code object. If NULL data is specified, the
code object is returned to its natural signing state (before a detached
signature was first attached to it).
Any call to this function voids all cached validations for the Code object.
Validations will be performed again as needed in the future. This call does not,
by itself, perform or trigger any validations.
Please note that it is possible to have multiple Code objects for the same static
or dynamic code entity in the system. This function only attaches signature data
to the particular SecStaticCodeRef involved. It is your responsibility to understand
the object graph and pick the right one(s).
@param code A Code or StaticCode object whose signature information is to be changed.
@param signature A CFDataRef containing the signature data to be used for validating
the given Code. This must be exactly the data previously generated as a detached
signature by the SecCodeSignerAddSignature API or the codesign(1) command with
the -D/--detached option.
If signature is NULL, discards any previously set signature data and reverts
to using the embedded signature, if any. If not NULL, the data is retained and used
for future validation operations.
The data may be retained or copied. Behavior is undefined if this object
is modified after this call before it is replaced through another call to this
function).
@param flags Optional flags. Pass kSecCSDefaultFlags for standard behavior.
